Merge 3. Improve performance by switching to less aggressive settings for RI_NUM_TESSELLATED_SEGMENTS and RI_MAX_SAMPLES. Ignored the WIN32 specific API decoration defines when doing the merge. Note the code is now optimised in riPath.cpp to change from RI_NUM_TESSELLATED_SEGMENTS to _QUAD, _CUBIC, _ARC settings which are each now set to 8. SVG Tiger now renders in 5 seconds (15 seconds quicker). The quality of the OVG icons is slightly reduced but still very useable.

/**
This class is a handle to a DirectGDI adaptation-specific resource that is bound 
to a non-image resource (RSgDrawable). The intention of creating this class is to allow 
a non-image resource (global and sharable between processes) to be used as a source from 
the DirectGDI rendering API. This class and its DirectGDI adaptation-specific resource are 
non-sharable and will be local to the calling thread.

This class is part of generic code and will forward creation and deletion requests
to the CDirectGdiDriver singleton object for the calling thread.
